I've been a developer/network admin in the Microsoft / IBM AS/400 world for about 15 years, and I've decided to leap into the world of Linux, which I know virtually nothing about.

I have a few ideas for some PDA applications that I was originally considering writing for Palm OS, but due to several hardware limitations, it appears that I'll have better luck with a Zaurus. So I'm going to pick up a C760 and setup a Linux PC to cut my teeth on...

I have some questions regarding how the Zaurus compares to other PDA's. I know these are very basic, but unlike most PDA's, I can't run down to my local computer store to put one in my hands, so I'll pose these questions to current Zaurus owners:

1. Does it turn on instantly, the way a Palm OS PDA does?
2. Can I turn it off and turn it back on right where I left off?
3. If so, will it reestablish a wifi connection after "waking up"
4. Can it automatically establish a wifi connection to a 'preferred' preconfigured wifi network once it detects one (the way WinXP does)?
4. Does the C760 have a built in microphone, or support for an external one? Is the Bluetooth Headset Profile supported?
5. Can I move files between an SD memory card and a CF memory card?
6. Could I 'stream' an MP3 from a network attached drive over wifi and listen to it? video?

Sorry, I know these are dumb questions, but these are basic issues that will affect my decision to purchase this pricey little gadget or not...

I am bummed that the SD slot doesn't support SDIO, do you think the next C7XX will support SDIO, and/or do you think it will have Bluetooth and wifi built in? What has been Sharp's typical time frame for releasing new Zaurus models?
